/*
 * /f1 — next race circuit page.
 *
 * Deliberately off-palette from the rest of jeremy.ie, the same way
 * eclipse-ireland-2026.css is: this one is built to read like a circuit print,
 * charcoal ground with a single accent line. What it does share is the site's font
 * trio and the .wrap / .kicker / .reveal conventions.
 *
 * That accent is per-circuit rather than fixed — see --accent below, and
 * CIRCUIT_COLOURS in f1-circuit.js for the palette itself.
 *
 * The poster's title face is a heavy geometric sans; Chivo Mono 700 uppercase on
 * wide tracking gets close enough to it that a fourth webfont isn't worth the load.
